[PATCH AUTOSEL 5.13 68/88] selftests/x86: Fix error: variably modified 'altstack_data' at file scope

by Sasha Levin

From: Jun Miao <jun.miao(a)windriver.com> [ Upstream commit a051b2e56f2aa287b37ab0134a8af852f84e3f8e ] A glibc 2.34 feature adds support for variable MINSIGSTKSZ and SIGSTKSZ. When _DYNAMIC_STACK_SIZE_SOURCE or _GNU_SOURCE are defined, MINSIGSTKSZ and SIGSTKSZ are no longer constant on Linux. glibc 2.34 flags code paths assuming MINSIGSTKSZ or SIGSTKSZ are constant. Fix these error in x86 test. Feature description and build error: NEWS for version 2.34 ===================== Major new features: * Add _SC_MINSIGSTKSZ and _SC_SIGSTKSZ. When _DYNAMIC_STACK_SIZE_SOURCE or _GNU_SOURCE are defined, MINSIGSTKSZ and SIGSTKSZ are no longer constant on Linux. MINSIGSTKSZ is redefined to sysconf(_SC_MINSIGSTKSZ) and SIGSTKSZ is redefined to sysconf (_SC_SIGSTKSZ). This supports dynamic sized register sets for modern architectural features like Arm SVE. ===================== If _SC_SIGSTKSZ_SOURCE or _GNU_SOURCE are defined, MINSIGSTKSZ and SIGSTKSZ are redefined as: /* Default stack size for a signal handler: sysconf (SC_SIGSTKSZ). */ # undef SIGSTKSZ # define SIGSTKSZ sysconf (_SC_SIGSTKSZ) /* Minimum stack size for a signal handler: SIGSTKSZ. */ # undef MINSIGSTKSZ # define MINSIGSTKSZ SIGSTKSZ Compilation will fail if the source assumes constant MINSIGSTKSZ or SIGSTKSZ.

[PATCH AUTOSEL 5.4 058/109] selftests/bpf: Fix xdp_tx.c prog section name

by Sasha Levin

From: Jussi Maki <joamaki(a)gmail.com> [ Upstream commit 95413846cca37f20000dd095cf6d91f8777129d7 ] The program type cannot be deduced from 'tx' which causes an invalid argument error when trying to load xdp_tx.o using the skeleton. Rename the section name to "xdp" so that libbpf can deduce the type.
